To all whom t may concern: j` y Beit known that I, WILLIAM'I-I. BOUTELLE., acitizen of the United States, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented certain new anduseful Improvements in Ophthalmic Mountings, of which the following Y is a specication.

This invention relates to new and useful improvements in ophthalmic mountings and more particularly to lwhat is known as a combined end piece and strap and the main o'bject of thepresent invention is the' pro-v vision of a combined end piece and strap provision of a one which is formed of a singlepieceofmaterial.l 'Y l. f

Another object of this invention is the iece combination end piece andstrap which is readily adapted for use upon either plain or toric.lenses and can be quickly andreadilyrapplied or `removed. v

A further object of the present inventionis thel provision of a mounting of the above character wherein the glass is self-locking and whengscrewed up tight .bindslboth side and edgewise on-the lens.

A still further ob'ect oftheinvention is the provision of a mounting of this character wherein the end-pieceis vwhat isulmown as an invisible end-piece and wherein the straps can be readilytightened toithe lenses by the turning of aV set s crew^ 'carried by the endpiece. .Y f

Another obj ect'of the invention is the ,provision of -amounting of the above character wherein the nose. bridge end lpiecesfand lensfstraps are Stampedfrom a single piece of material. v

With the above and other objects ink view thevinvention consists inthe novel features of construction and the combination and arrangement of parts` to be hereinafterimore fully described, pointed out inthe claims and shown in the accompanying drawings, inwhichV v Figure I is. an .opththa'lmic mounting cons tructedA in accordance with my invention.

'Incarrying out my invention thenose bridge and end straps are formed of a single Y vpiecefof material stamped Vout, in one-operation and includes the nose piece l from Vwhich extend vthe upwardly projecting arms 2 having their endseXtended outwardly Vat which have formedY therein -fth'e elongated upon themselves as` shownV in Fig. lI Iand tremities of the arms v3 and intovtheinner ends of the arms atyagpointadjacent Vvthe Yslots 4:.' -The'armsf are 'adapted to bebent i 10o'k Y right angles to providethe strap 'arms Y l outer ends of the arms 2.

the screw "7 is clearly 'illustrated in Fig. XIII, but while this particular screw-"is not showngin this View it is one upon which .the

` tapering nut is used,`

When the straps 6 are formed the side lof the end piece portions, formed by the slots 4 are disposed inparallellrelation as shown at 13 while the intermediate portionsthereof are looped asfshown at 9V toreceive the screws 7V and from? this it .be apparent that Vbythe tightening. of' the screws. 7 the parallel portions are forcedjapart which ai?h f tion in addition yto the-:binding vtuition of the j tapering nut will draw the loops 9y inwardly lofthe lens.

In Fig. XIII I have shown a cross section through a lens showing the relative position of the tapering nut 12 with respect to the wall of the opening in the lens andshowing how the tightening of the nut will tend to draw the lens in toward the mounting and into engagement with the stud 8.

From the above description taken in connection with the accompanying drawings` consists in forming lthe temple end piece out of a single piece including the straps and means for pivotally connecting the temple with the straps. AIt will be notedthat the'temple end piece can be constructed in various ways without departing from the scope of the invention.

` In the main form of the invention as well as in the various modifications illustrated in Vthe accompanying drawings I have shown the projections -A-- formed on the side portions of the slotted blank which are adapted to fill-the space in the loop adjacent the screw member when applied to the lens thus closing all cavities which would be liable to catchany dust or dirt should they remain unlled.

I claim: Y

l. A one-piece member including a nose bridge, an arm extending from each end thereof, having a slot therein forming parallel side portions adapted torform loops when theV arms are bent upon themselves.

2. A one-piece member including a Vnose bridge, an arm extending from each end thereof, havin a slot therein forming parallel side portlonsadapted to form,` spaced loops when the arms are bent upon themselves and fingers extending from each side of the arms as and for the purpose set forth.

' and tapering members carried by said screw member as and for the purpose set forth.

7. A d'eviceof the class described, including an elongated member having a central slot to receivethe lens, said member being bent upon itself whereby the folds willfengage and retain a lens screw.

, 8. A device of the class described, including an elongated member having a central ing an elongated member having a slot to receive the lens. said member being bent :slot to receive the lens, said memberbeing f bent upon itself whereby the sideportlons upon itself whereby the folds will engage and retain a lens screw, andperforated' ears at each end of the body.

10. A .device of the class described,r including an elongated member having a central slot to receive the lens, said member being bent upon itself, whereby the folds will engage and retain a lens screw, and
